MATTRESS-MAKING APPARATUS.

Application filed September 1, 1927. Serial No. 216,831.

uniform thickness. It is anobject of this in-' vention to distribute the cotton, as it comes from the gin, uniformly over the entire area of the compressor box.

Another object is to effect this by a comparatively simple construction.

Further objects and advantages will appear in the subjoined detailed description.

The accompanying drawings illustrate the invention.

Figure 1 is a side elevationof a mattressmaking apparatus constructed in accordance 7 with the provisions of this invention.

Figure 2 is a plan view, partly in section on the line indicated by 2-2, Figure 1. I

Figure 3 is an enlarged sectional detail on the line indicated by 33, Figure 2.

Figure 4 is an enlarged fragmental elevation, partly in section, from the line indicated by 44, Figure 2.

Figure 5 is a vertical section on the line indicated by 55, Figure ,1, the sides of the compressor box being indicated in one position in solid lines and in another position in broken lines. y

Figure 6 is a sectional view taken on the line 66 of Figure 4. i I

A compressor box is indicated in general by the character 6, and is of the usual construction, the side walls havinghinged sections 7, 8 so thatthe lower portion of the box may be contracted for producing mattresses of different width. The top wall has a perforate portion, as shownin Fig. 2, to permit of the exhaust of air from the box.

A cotton gin, indicated in general by the character 9, is mounted adjacent to the compressor box upon a suitable support 10. The cotton gin is of the usual construction and some of the interior thereof is shown in the drawings. In Figure 3 may be seen one of the saws 11 and the rotary brush 12 that brushes the cotton off of the saws. moves past a passage 13 that communicates The brush 12' with the compressor box through one wall thereof. The brush 12 is mounted on a shaft 14 supported at its ends in bearings 15. The shaft 14 is provided with a pulley 16 driven by a belt 17 from a pulley 18 mounted one. 1

shaft 19. The upper run of thelbelt 17 engages theunder side of the pul1ey16 and passes around an idler pulley 191 so as to effect driving of the brush 12 clockwise'so that said brush will operate properly to brush fibers from the teeth of the saws 11 which ro- F tatecounterclockwise. This is the usual construction of cotton gins. The shaft'19 is provided with a pulley 2O driven by a belt 21 from a pulley 22 which is mounted on the shaftof the-motor 23. Thus, operationof theshaft 19 effects operation of the gin.

Movably mounted within the compressor box adjacent to the discharge end of the passage 13 is a cotton-distributing shield or deflector 24 which, in this instance, is concave on the face turned toward the passage 13. The deflector 24 is fixed to a rock shaft 25 that turns in bearings 26 mounted on the sides of the compressor box. Fixed to the shaft 25 is an arm 27 to which is pivoted at 28 a pitv man 29. The pitman 29 is pivotally connected at 30 to a rotary member that is in the.

form of a .disc 31. The stroke of the'pitman 29 may be lengthened or shortened by reason of the pivot 30 being adjustably mounted in I a radial slot 32 in the disc 31. Lengthening and shortening of the stroke of the pitman 29 produces lengthening and shortening,'respectively, of the stroke of the deflector 24. The deflector 24 swings in an arc toward and from the. discharge end of the passage 13 and, in Figure 3, said deflector is shown in an intermediate position in solid lines and is indicated in, broken lines in two other positions, one below and one above the intermediate position.

on the support 10. Fixed to the shaft 33 is a worm gear 35 in mesh with a worm 36 on a worm shaft 37. The shaft 37 1s driven by a worm gear 39 in mesh with a worm 40 that is thrown by the brush 12 into and through the passage 18, the current of air set up by the whirling brush aiding materially in movthe cotton into the compressorbox. As suming that the deflector 24 is in the lowermost position, indicated in broken lines in Figure 3, the cotton will strike said deflector and be deflecteddownwardly along that side of the box that is nearest to the passage 13. As the cotton Continues to discharge into the box, the arm24 slowly moves forwardly and upwardly, thuscausing the cotton that strikes the deflector to be spread uniformly in a layer of given thickness extending away from the box wall that is nearest to the passage 13.

Finally, the deflector 24 reaches such a posi tion, its extreme upper position, that the cotton is deflected thereby to the farther side of the box. The deflector then begins to move on its return stroke, thus forming another layer of cotton. The cotton continues to discharge into the box and the deflector 24 continues to rock to form successive layers of the cotton. in the box until the number of pounds of cotton that the mattress is to contain has been discharged into the box. The cotton bat thus formed is then compressed in a manner well understood in this art and, therefore, not necessary to describe, as it constitutes no part of this present invention which relates only to the distribution of the cotton in the compressor box.

I claim:

I 1. A mattress-making apparatus compris ing a box, a passage for cotton communicating. with the interior of the box through one wall thereof, a means to feed cotton through the passage, a movably mounted deflector in the box adjacent to the passage, and a means to move the deflector into different positions passage, a deflector mounted to rock in the box ad acent to the passagaand a means to rock thedeflector to distribute the cotton in having concave face turned toward the passage, and a means to roclrthe deflector to distribute the cotton in the box as it leaves the passage, the deflector extending substantially to said box wall at a level higher than the discharge end of the passage so as to de flect the cotton downwardly. .41. A mattress-making apparatus comprising a box, a passage for cotton communicating with the interior of the box through one wall thereof, a means to feed cotton passage, a deflector mounted to rocl in the box adjacent to the passage,and a means operably connected with the cotton-feeding moans ano including speed-reduction gearing for rocking the deflector to distribute the cot deflector mounted to rock in the 7 tirough the ton in the box as it leaves the'passage, the

deflector extending substantially to said box wall at a level higher than the discharge end of the passage so as todeflect the cotton downwardly. 1 v

5. A mattressmaking apparatus compris in g a box, a passage for cotton communicating with the interior of the box through one wall thereof, a means to feed cotton through the passage, and a means extending from sai d box wall toward the opposite wall and downward ly, to direct the c ottonas it leaves said passage toward the bottom of said b K, said last named means including a movable member, and a. 'means operable to move the movable 'member into difierent angular positions to direct the cotton into different portions of the box.
